Description
M/A-COM's MAATCC0014 is a GaAs FET 5-bit
digital attenuator with integral TTL driver. Step size
is 0.5 dB providing a 15.5 dB total attenuation range.
This device is in an PQFN plastic surface mount
package. The MAATCC0014 is ideally suited for use
where accuracy, fast speed, very low power
consumption and low costs are required. For dual
supply designs without switching noise, use
MAADCC0012.

1. Pins 10 and 29 must be isolated.
2. VEE is produced internally and requires a .1 µF cap to GND.
Generated noise is typical of switching DC-DC Converters.
3. The exposed pad centered on the package bottom must be
connected to RF and DC ground. (For PQFN Packages)

4. During turn-on, the device requires an initial start up current (Icc) specified as —Turn-on Current“. Once operational, Icc will
drop to the specified levels.
5. The DC-DC converter is guaranteed to start in 100 µs as long as the power supplies have the maximum turn-on current
available for start-up.

Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.

-65ºC to +125ºC
6. Exceeding any one or combination of these limits may cause
permanent damage to this device.
7. M/A-COM does not recommend sustained operation near
these survivability limits.
8. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
